i and particularly to means for subjecting the lao open top lled canstoa vacuum; and the object o1 the -invention is to produce a simple andIeilicient apparatus for this purpose.

The invention contemplates, a long recs tangu1arshaped'box, a door toreach end, 2li

a plurality' of rollers arranged transversely 'along the bottom of thisbox, and onvvhich trays bearing a number of the lledopen top cans may berolled into and out of the box, a pipe provided with a valve connecting'the interior of this box with a suitable air exhausting device, andmeans for breaking the vacuum, as will hereinafter more tullyappear.. 1

rl'heinventlorrconslsts.1n thenovel construction and combination ofparts, reference being had to the accompanying drawings, :terminar apart of this specification, in

Which- A Figure 1 represents in side elevation a preferred form ofapparatus embodying my present invention.

Fig. 2 is a section on the line A-A of Fig. 1.

Referring to the drawlngs, 5 is the long rectangular shaped boxpreferably of cast.v

iron. Each of the doors 6, for closing the ends of the box 5, arehingeably mounted between the outer ends of the arms 7 and 8 on oppositesides of the box 5 respectively. 'lhe arms 7 are pivoted on lthe pins `9in the sides of the box 5. The arms 8 are piv- 'oted on the pins 1() inthe lugs aon the top of the box-V5. Each of the arms 8 is extended at'8a and provided with aweight VV 11 to Aceunterweight the doors 6. Eachdoor '"6 may-#Ehns be, swung` upward to provide access'tothe interio'rofthe box 5..4 A gasket 12 may be interposed between the end vof 'openingthe valve 19.

theibox 5 and a door 6 to seal the joint when the door is closed.

A plurality of rollers 13, each provided "with trunnions 11 adapted toturn in the notches 15 in the two rectangular bars 16, are arrangedtransversely within the box 5, as shovvn.

The pipe 17, provided with the valve 1 8,

connects the interior of the box 5 with asuitable air exhausting device.The valve 19, connected by the nipple 2() to the box 5, may be used forbreaking the vacuum Within the box 5. lin operation, a door 6 is raised,a tray 2 bearing thereon a number offilled open top cans 22 is pushedinto the box 5, and then other trays successively until the box 5 isfilled, the trays moving easily upon the rollers 13. -One tray 21 isshown in the draw# 4Spearman. or auraient. Patented Fango, new, y

ings having thereon a'dozen cans '22 although more or less vcans may ofcourse be thus handled. When the box 5 has been filled as described, thedoor 6 is then lowered until closed, the valve 19 being closed the valve18 is now opened. The box 5 is thus evacuated to withdraw the air andgases from the fruit inthe cans as well as the air frolnpwithin the box5, r1`he valve .18 is then vclbsed, and the vacuum is broken by Bothdoors-filiy are now swung upward and the trays bearing the treated cansvare pushed forward and rolled outward upon the rollers 13 and'discharged from the box 5 by the insertion of anew set of traysbearingother cans which are to be similarly treated.'
